There are many ways to free up space on your Windows 10 PC's system disk when it starts to become saturated. But perhaps the best way to do it quickly is to find the largest files and delete them or transfer them to another storage device.
Find out how to find the largest files on Windows 10.
Start by opening a Windows file explorer window. You can use the keyboard shortcut Windows+E, or click directly on the shortcut in the taskbar.
Then select the storage media you wish to work on. Stay on This PC if you want to search for files on all storage devices on your computer, or select disk C: if you only want to search for large files on the disk containing the operating system.
Activate the cursor in the search field of the file explorer
Then click the Size drop-down menu to instruct Windows to search for other files in different sizes, such as Huge, for files between 1 and 4 GB.
Now all you have to do is delete or move the found items to another storage device to free up space on your primary drive.
